To all whom. it may concern..-

Beit known that LWILHELM LENGWEILER, a citizen of Switzerland, residing at Wangen, Algau, in the Kingdom of Wrtemberg and Empire of Germany, have invented certain new and useful Improvements in Ring-Spin` ning Machines, (patented to me in Great Britain, patent dated March 19, 1898, No. 6,722;) and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will -enable others skilled in the art to which it appertains to make and use the same. v

The subject of the present invention is an improvement on the ring-spinning machine described in my application,Serial No.626,257, iiled March 6, 1897, for spinningany desired cops upon the same spindle like in form and construction to self-actor cops. According to the disclosure in said application the production of cops like self-actor cops upon a ring-spinning machine is possible only with three mechanisms-viz., (a) a speciallyformed cam L, whichv moves the ring-frame in a suitable manner up and down for thev formation of each height of winding of the cop (h) an also specially-formed chain-winding cam S with a nose s, wherebylhe'copwindings have an exact conical form instead of the usual ovoid form and the cops have a cylindrical outer form notwithstanding the alteration in the heights of thestrata of windings, and (c) a special support P, with an angle-slot for controlling the draft-chain in order to gradually reduce the heights of the cop-windings Which follow one after the other after the base-cone of the cop has been finished.

The object of the present invention is `to simplify, essentially, the invention disclosed in said application by substituting for the specially-constructed cams L and S and the traveling support P a suitably-formed camdrum L', which occupies the relative position of the cam L previously employed and which cam-drum is shifted axially during the for-l mation of the cop, so that continuously another part of said cam-drum is brought into contact with a roller n,',which moves the lever N or the frame D toand fro during the formation of each stratum of the cop. The chain-actuating'roller S, on the contrary, is

constructed again in its usual circular form.

Instead of two chains R andA R only one is applied in the present construction for the operation of the frame, this chain passing over a sheave r.

The improved cam-drum shown in the accompanying drawings consists of a series of cams which are to be considered as so constructed and placed side by side that at the commencement of the formation of the cop a nearly uniform and small rising and sinking of the ring-frame take place. Then the heart-cam producing this movement gradually increases progressively in eccentricity, conforming to the conical layers of the cop,`and finally the eccentricity is reduced to produce the shorter conical portion of the cop. The cam-drum so constructed must then be shifted by a slide mechanism, or if the drum is not movable the roll for transmitting the drum movement located on the controlling-lever must be arranged to be shifted. The formation of the swell of the cop is obtained by the lowest or smallest diameter of the cam-drum, the tight winding of the point of the cop by the greatest diameter of the said cam-drum, while by means of the draft apparatus, as formerly, a uniformly-varying draft of the chain is produced. By this construction all movements of the ring-frame and cop-building mechanism are produced in an extremely simple manner,so that'the chain transmits the movement direct from the lever to the ring-frame, being led over a pulley r, thus avoiding the use of the nose r3, employed in my previous construction.

'In the drawings, Figure l is a side elevation of so much of a ring-spinning machine as is necessary toillustrate my invention; Fig.

2, a detail side elevation of the cam-drum and lever-moving mechanism; Fig. 3, a detail sectional view showing a modified construction. Fig. 4f, two detail views of the mechanism on the end of the lever, the left-hand view being a transverse section of the right-handvview,

`which latter is a plan of the said mechanism;

and Figs. 5 and 6, a series of diagrammatic views illustrating the elements of the camdrum.

The construction illustrated in the views is an example of an apparatus and cam-drum adapted for the production of cops of No. 2O English lor sixty-five grains weight.

ICO

In Fig. 6 are shown a number of cross-sections of a cam-drum.

Fig. 5 shows the cross-section of a theoretically-calculated winding-body wound with yarn of a certain ber laid on in normal density. The amount of shifting calculated for each certain number of windings and the different heights of the windings give in their projection the necessary eccentricity and correction for shifting for the eam-drum--that is to say, the highest and lowest points on the same. The slope of the cone, which is gradually formed upon the spindle for each instant of the cop-winding, gives the form of the increasing and decreasing spirals required by the fourteen cam shapes shown in Fig. 6,whieh produce a proportional reverse movement of the ring frame. These fourteen profiles, placed side by side at certain intervals, determine all the points in the envelop of the camdrum. Vhile the cops are being formed the different profiles of the cam-drum must be transferred to the controlling-lever, which causes the movement of the ring-frame. This maybe done in two ways, as will now be pointed out.

Fig. 2 shows the cam-drum L in the position of the former eccentric L. (Shown in my application previously filed.) A roller L2 (shown in Fig. 4) runs in contact with the periphery of the cam-drum, said roller L2 being movable along a spindle N', situated on the lever N. The said roller moves in slideways axially to the cam-drum L'. The moving of this roller or the moving of the lead screw or spindle N', to which it is connected, is accomplished in a simple manner by means of gears from the front of the apparatus, so that by the change f gears the movement of the chain and also the movement of the roller are varied. In this construction the roller L2 moves along the different profiles of the cam elements which go to make up the cam-drum.

In Fig. 3 the construction is such that the roller is stationary, while the cam-drum is shifted with relation thereto longitudinally. The cam-drum is mounted upon a hollow slotted shaft L3, which is driven from the main mechanism in any suitable way. This hollow shaft L3 imparts rotary motion to the camdrum, while the axial shifting of the same is accomplished by a lead screw or spindle N', located inside of the hollow shaft and rotated slower than said shaft by suitable gears. The cam-drum is connected to and moved by the lead screw or spindle through the medium of traveling nuts L4, mounted on the spindle and connected to the cam-drum by arms passi ing through the slot in the hollow shaft.

The surface or periphery of the cam-drum is, briefly stated, of a contour or shape from end to end corresponding to a circular cam, having the greater part of its periphery of gradually-increasing radii and the remaining part thereof of gradually-decreasing radii.

1When other numbers are to be spun, suitable changes may be made in the gears.

For producing larger or smaller cops upon the same spindles it is only necessary, as in the selfactor or mule, to change the rings and gears.

The mechanism above described may of course be somewhat modified, being presented herewith merely as one example of my invention. y

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

l. In a ring-spinning machine, the combination with a ring-frame, of a rotary camdrum having its periphery at one end of relatively small eccentricity this eccentricity iirst increasing and then decreasing toward the other end of the drum, means actuated by the cam-drum for transmitting a reciprocating motion to the ring-frame according to the profile of the cam-drum, mechanism for shifting the said means and the cam-drum with relation toeach other in the direction of the axis of the cam-drum, whereby a varying reciprocation of the ring-rail frame is produced, and means for shifting the terminal points of said reciprocations of the ringframe,wherebya movement of the ring-frame is produced which is inversely proportional at each moment to that part of the cop being wound.

I'n a ring-frame, the combination with a lever, a chain-winding gear carried by said lever, a ring-frame, and a chain connecting the ring-frame and the chain-winding gear, of a rotary cam-drum having its periphery at one end of relatively small eccentricity, this eccentricity first increasing and then decreasing toward the other end of the drum, means intermediate the cam-drum and lever for transmitting a reciprocating motion to the le-y ver, according to the profile of the drum, and mechanism for` producing a relative movement between the said means and the drum in the direction of the axis of said drum, whereby a reciprocating movementof the ringframe is produced, the speed of said movement being at all times inversely proportional to the diameter of that part of the cop at that time being wound.

In testimony whereof I affix my signature in presence of two witnesses.
